I am currently studying for my private pilots license in the UK. When I am flying I ask the local RAF station for a basic service. My question is how do I know what service I can get from an aerodrome by looking at a map? I have noticed LARS which is lower airspace radar service and also VDF which is to do with VHF direction finding?
If I however require a basic service, a procedural service or a traffic service then how can I find out if the service is offered. I considered checking the AIP but its no good if I am in the air.
